Description

Title of Invention: SWEETENER COMPOSITION AND METHOD FOR
IMPROVING TASTE OF STEVIA EXTRACT
Technical Field [0001]
The present invention relates to a sweetener composition, and a composition that is orally administered or used for the oral cavity comprising the same. Further, the present invention also relates to a method for improving the taste of stevia extract.
Background Art [0002]
Conventionally, sweeteners have been widely used to impart sweetness to foods, beverages, and medicines, as well as to adjust their taste. In particular, due to the recent rise in health concerns, non- or low-calorie high-intensity sweeteners, and high-intensity sweeteners with low caries-producing effects have been widely used. Examples of high-intensity sweeteners include synthetic sweeteners, such as aspartame, sucralose, acesulfame potassium, neotame, and advantame; and natural sweeteners, such as stevia extract, siraitia grosvenorii extract, and thaumatin. As a result of the recent trend towards natural products, natural sweeteners, such as stevia extract and siraitia grosvenorii extract, have become favored.
[0003]
However, these natural sweeteners, particularly stevia extract, have a sweetness quality different from that of sugar, and have problems such as bitterness in their sweetness, a lingering sweetness (remaining sweetness) left in the mouth, a lack of richness in their sweetness, slow sweetness expression in the oral cavity, and insufficient sweetness quality. Rebaudioside A, which is a main sweetness component contained in stevia extract, has less lingering sweetness and rough taste, such as
-2.bitterness, compared with other sweetness components, such as stevioside, in the stevia extract; however, rebaudioside A still has the above problems. Moreover, mogroside V, which is a main sweetness component of siraitia grosvenorii extract, also has problems such as bitterness and unique flavor.
[0004]
In order to solve these problems of stevia extract, conventionally, there have been proposals, for example, for methods using stevia extract in combination with a rutin derivative (PTL 1), royal jelly (PTL 2), quinic acid (PTL 3), cellooligosaccharide (PTL 4), vicenin-2 contained in fruit juices of citrus (PTL 5), or the like. Moreover, PTL 6 proposes a method for improving the taste of stevia extract by mixing thaumatin at a specific ratio relative to the stevia extract. Further, PTL 7 indicates that a composition having an excellent sweetness quality is obtained by mixing rebaudioside A, which is a main sweetness component of stevia extract, with mogroside V, which is a main sweetness component of siraitia grosvenorii extract, at a weight ratio of 95:5 to 60:40. In addition, PTL 8 discloses a composition comprising mogroside V and a rebaudioside component, such as rebaudioside A, at a weight ratio ranging from 1:1 to 6:1.

-3Summary of Invention
Technical Problem [0006]
An object of the present invention is to provide a technique for improving the sweetness quality of stevia extract or its sweetness component (rebaudioside A) using natural sweetener components .
More specifically, a first object of the present invention is to provide a method for improving the sweetness quality of rebaudioside A, which is a main sweetness component of stevia extract; a sweetener composition whose sweetness quality has been improved by the method; and a composition orally administered or used for the oral cavity, such as a food or beverage, comprising the same. A second object of the present invention is to provide a method for improving the sweetness quality of stevia extract; a sweetener composition whose sweetness quality has been improved by the method; and a composition orally administered or used for the oral cavity, such as a food or beverage, comprising the same.
Solution to Problem [0007]
The present inventors conducted extensive research to achieve the above objects, and consequently found that rebaudioside A, which is a main sweetness component of stevia extract, was mixed with a slight amount of mogroside V, which is a main sweetness component of siraitia grosvenorii extract, so that the proportion of rebaudioside A to mogroside V was 95:5 to 99:1 (mass ratio), whereby the problems (bitterness, lingering sweetness, lack of richness, and slow sweetness expression) of the sweetness quality of stevia extract and its main sweetness component, rebaudioside A, were reduced or solved, and a composition having excellent taste closer to that of sugar was obtained. In particular, it was confirmed that the combined use of rebaudioside A and mogroside V with the above proportion
-4accelerated the expression of sweetness in the oral cavity and enhanced richness, thereby synergistically solving the problem of stevia extract, i.e., insufficient sweetness quality. These results suggest that the use of this composition as a sweetener can impart excellent sweetness to various products, such as foods and beverages, drugs, and quasi-drugs, which are orally administered or used for the oral cavity.

Advantageous Effects of Invention [0011]
The method for improving the taste of stevia extract of the present invention can improve problems in the sweetness quality of stevia extract (e.g., bitterness, lingering sweetness, a lack of richness, and slow sweetness expression), and can provide a sweetener composition having an excellent sweetness quality closer to that of sugar using stevia extract, which is a natural sweetener, as a raw material. Moreover, the method for improving the taste of stevia extract of the present invention can improve the slow expression of sweetness in the oral cavity, which is a drawback of stevia extract, to accelerate the sweetness expression, thereby reducing or solving problems, such as insufficient sweetness quality and lingering sweetness (remaining aftertaste).
[0012]
As a result of improvement in the problems (e.g., bitterness, lingering sweetness, lack of richness, and slow sweetness expression) of the sweetness quality of stevia extract and its sweetness component, stevioside A, the sweetener composition of the present invention has an excellent sweetness quality close to that of sugar. Accordingly, the sweetener composition of the present invention can impart an excellent sweetness quality to various compositions orally administered or used for the oral cavity.
Description of Embodiments [0013] (I) Sweetener Composition
The sweetener composition of the present invention
-7(hereinafter simply referred to as the present sweetener composition) is characterized by comprising rebaudioside A and mogroside V at a mass ratio of 95:5 to 99:1.
[0014] Rebaudioside A
Rebaudioside A is a steviol glycoside contained in stevia extract, and is known, as a main sweetness component of stevia extract, to have a degree of sweetness 300 to 450 times that of sugar. Rebaudioside A can be prepared by extraction from leafs, stems, or the like of Stevia rebaudiana Bertoni (abbreviated as stevia in the present invention), which is a plant belonging to the genus Stevia, family Compositae, with water or an organic solvent, followed by purification. The rebaudioside A targeted by the present invention includes enzymetreated rebaudioside A obtained by transferring sugar, such as glucose or fructose, to rebaudioside A using aglucosyltransferase or the like.
[0015]
In the present sweetener composition, rebaudioside A may be used in a purified state, but is not limited thereto. To the extent that the working effect of rebaudioside A in the present sweetener composition is not prevented, rebaudioside A can also be used as a mixture with other steviol glycosides (stevioside, rebaudioside B, rebaudioside C, rebaudioside D, rebaudioside, dulcoside A, rubusoside, steviolbioside, etc.). Preferable examples of such mixtures include stevia extract. The stevia extract includes enzyme-treated stevia obtained by transferring sugar, such as glucose or fructose, to the stevia extract mentioned above using α-glucosyltransferase or the like. When such a mixture is used, the content of rebaudioside A in the mixture is preferably 90 mass% or more, and more preferably 95 mass% or more, of the total amount. This is because if the content of components other than rebaudioside A in the mixture increases to more than 5 mass%, the influence of these components on the taste of the present sweetener composition cannot be
-8ignored. Preferable examples of the mixture include, but are not limited to, stevia extract containing rebaudioside A in an amount of 95 mass% or more of the total amount, and other steviol glycosides, as other components, in a total amount of 1 mass% or less, and more preferably stevioside and rebaudioside C in a total amount of 0.2 mass% or less.
[0016]
The rebaudioside A can be prepared by subjecting leaves, stems, or the like of Stevia Rebaudiana Bertoni as raw materials to extraction and purification. Simply, commercially available products can also be used. Examples of such products include Rebaudio J-100 (produced by Morita Kagaku Kogyo Co., Ltd.) and the like. This product is a rebaudioside A-containing product (stevia extract) comprising 95 mass% or more of rebaudioside A.
[0017]
Mogroside V
Mogroside V is a triterpene-based glucoside contained in siraitia grosvenorii extract, and is known, as a main sweetness component of siraitia grosvenorii extract, to have a degree of sweetness about 300 times that of sugar. Mogroside V can be prepared by extraction with water from raw fruits of Rakanka (scientific name: Siraitia grosvenorii), which is a plant belonging to the genus Siraitia, family Cucurbitaceae, followed by purification.
[0018]
In the present sweetener composition, mogroside V may be used in a purified state, as with rebaudioside A, but is not limited thereto. To the extent that the working effect of mogroside V in the present sweetener composition is not prevented, mogroside V can be used as a mixture with other triterpene-based glycosides (mogrol, mogroside IEi, mogroside IAi, mogroside HE, mogroside III, mogroside IVa, mogroside IVE, simenoside, 11-oxo-mogroside, and 5a,6a-epoxymogroside). Preferable examples of such mixtures include siraitia grosvenorii
-9extract. When such a mixture is used, the amount of mogroside V in the mixture is preferably 30 mass% or more, and more preferably 50 mass% or more, of the total amount. This is because if the contents of components other than mogroside V in the mixture increases, the influence of these components on the taste of the present sweetener composition cannot be ignored.
[0019]
The mogroside V can be prepared by subjecting fruits of Siraitia grosvenorii as raw materials to extraction and purification, as described above. Simply, commercially available products can also be used. Examples of such products include, but are not limited to, high-purity siraitia grosvenorii extract containing a high purity of mogroside V and having a degree of sweetness about 300 times that of sugar (produced by Saraya Co., Ltd.).
[0020]
Present Sweetener Composition
The present sweetener composition is characterized by comprising rebaudioside A and mogroside V at a mass ratio of 95:5 to 99:1. The proportion of rebaudioside A to mogroside V is preferably 95:5 to 98:2, and more preferably 96:4 to 98:2, by mass ratio. As shown in Experimental Examples, provided later, when the amount of mogroside V is less than 1 part by mass and more than 5 parts by mass based on 100 parts by mass of the total amount of rebaudioside A and mogroside V, the effect of improving the sweetness quality of rebaudioside A cannot sufficiently be obtained. Moreover, because mogroside V is expensive, use of more than 5 parts by mass of mogroside V causes a problem of increasing product costs.
[0021]
The present sweetener composition can be produced by mixing rebaudioside A and mogroside V at the ratio described above. The present sweetener composition can also be produced by using the above-mentioned stevia extract comprising 95 mass% or more of rebaudioside A, and mixing it with mogroside V so that
-10the mass ratio of rebaudioside A to mogroside V is, as described above, 95:5 to 99:1, preferably 95:5 to 98:2, and more preferably 96:4 to 98:2. As the mogroside V used herein, siraitia grosvenorii extract comprising mogroside V as a main sweetness component can also be used, to the extent that the effects of the present invention are not impaired. Thus, the defects (bitterness, lingering sweetness, lack of richness, and slow sweetness expression) of the sweetness quality of stevia extract can be improved, and a sweetener composition having an excellent sweetness quality closer to that of sugar can be obtained.
[0022]
The present sweetener composition is used to impart sweetness to, for example, a target composition that is orally administered or used for the oral cavity, described later. There is no limitation to the form thereof, and the present sweetener composition may take any form, including a solid form, such as a powder, a granule, a tablet, or a capsule; or a semi-solid or liquid form, such as a syrup, an emulsion, a liquid, or a gel. Moreover, the present sweetener composition may take a singleagent or two-agent form.
[0023]
When the present sweetener composition is produced by mixing rebaudioside A and mogroside V at the ratio described above (or by mixing stevia extract with mogroside V so that the proportion of rebaudioside A to mogroside V satisfies the abovedescribed proportion), pharmaceutically acceptable carriers or carriers that can be added to foods and beverages can be suitably added, depending on the form thereof. Examples of such carriers include, within a range that does not affect the taste of the present sweetener composition, oligosaccharides, such as isomaltoligosaccharide, galacto-oligosaccharide, and fructooligosaccharide; polysaccharides, such as dextrin, cellulose, gum arable, and starch (e.g., corn starch); water; and the like. Moreover, to the extent that the taste of the present sweetener composition is not affected, mixing of the following components
-Ills not excluded: saccharides, such as lactose, glucose, fructose, sugar, and high-fructose corn syrup; sugar alcohols, such as sorbitol, erythritol, lactitol, maltitol, mannitol, xylitol, and reduced-palatinose; synthetic sweeteners, such as aspartame, sucralose, acesulfam potassium, saccharin, and salts thereof (e.g., sodium saccharin and calcium saccharin); natural sweeteners, such as licorice extract, amacha extract, brazzein, neohesperidine dihydrochalcone, serendipity berry extract (monellin), and tenryocha extract. Further, flavors, colorants, acidulants, preservatives, and other components that are ordinarily used for foods, beverages, or medicines may be added within a range that does not affect the taste of the present sweetener composition.
[0024]
The total ratio of rebaudioside A and mogroside V in the present sweetener composition can be suitably set within a range of 0.2 to 100 mass%, depending on the purpose of using the present sweetener composition, the use mode thereof, the presence or absence of other sweetness components, and the like. Since the degree of sweetness of the mixture (100 mass%) comprising rebaudioside A and mogroside V at the ratio described above is about 150 to 450 times that of sugar, for example, when the total amount of sugar in an orally administered composition is replaced by the same amount of the present sweetener composition, the total ratio of rebaudioside A and mogroside V contained in the present sweetener composition can be suitably adjusted within a range of about 0.2 to 0.7 mass%. Moreover, for example, when the present sweetener composition is directly used as a tabletop sweetener, the total ratio of rebaudioside A and mogroside V in the present sweetener composition can be suitably adjusted within a range of about 0.2 to 7 mass%, although it is not limited thereto. In this case, the present sweetener composition, in the same amount as sugar, has a degree of sweetness 1 to 10 times that of sugar; thus, sweetness similar to that of sugar can be obtained when the present sweetener composition is used in the
-12same amount or up to 1/10 the amount of sugar.
[0025] (II) Composition Orally Administered or Used for the Oral Cavity
The composition orally administered or used for the oral cavity of the present invention (hereinafter abbreviated as the present oral composition) is a composition having sweetness and comprising rebaudioside A and mogroside V at a mass ratio of 95:5 to 99:1. To this limitation, the present oral composition may contain mogroside V and stevia extract comprising 95 mass% or more of rebaudioside A. The proportion of rebaudioside A to mogroside V is preferably 95:5 to 98:2 (mass ratio), and more preferably 96:4 to 98:2 (mass ratio). The present oral composition can be easily prepared by adding and mixing the present sweetener composition described above to a target composition orally administered or used for the oral cavity described later.
[0026]
The present oral composition targeted by the present invention is a composition that needs sweetness. Examples of such compositions include foods and beverages; orally administered medicines; medicines for the oral cavity; and oral care products, such as dentifrices and mouthwashes (including drugs or quasi drugs).

[0029]
The present oral composition comprises rebaudioside A and mogroside V so that the proportion thereof falls within the above-mentioned range, and so that the final total concentration thereof in the present oral composition is 10 ppm to 5000 ppm. The final total concentration is preferably 25 ppm to 3000 ppm, and more preferably 50 ppm to 2000 ppm, although it varies depending on the type of the target present oral composition. Rebaudioside A and mogroside V may be added to a composition orally administered or used for the oral cavity at any step of its production.
[0030] (III) Method for Imparting Sweetness to Composition Orally Administered or Used for the Oral Cavity
The method for imparting sweetness to a composition orally administered or used for the oral cavity of the present invention can be carried out by adding rebaudioside A and
-14mogroside V to the compositions orally administered or used for the oral cavity targeted in (II) above at a mass ratio of 95:5 to 99:1. As the rebaudioside A, stevia extract comprising 95 mass% or more of rebaudioside A can also be used. The proportion of rebaudioside A to mogroside V is preferably 95:5 to 98:2 (mass ratio), and more preferably 96:4 to 98:2 (mass ratio).
[0031]
The amounts of rebaudioside A and mogroside V necessary to impart an excellent sweetness quality similar to that of sugar to these compositions orally administered or used for the oral cavity vary depending on, for example, the type of the target composition; however, the total amount of rebaudioside A and mogroside V is generally 10 ppm to 5000 ppm, preferably 25 ppm to 3000 ppm, and more preferably 50 ppm to 2000 ppm.
[0032]
In the sweetness-imparting method of the present invention, rebaudioside A and mogroside V may be independently added to a target composition orally administered or used for the oral cavity so as to satisfy the above-mentioned proportions and amounts. Alternatively, the present sweetener composition described in (I) above may be added to a target composition orally administered or used for the oral cavity so as to satisfy the above-mentioned amounts .
[0033] (IV) Method for Improving Taste of Stevia Extract
The method for improving the taste of stevia extract of the present invention can be carried out by mixing stevia extract comprising rebaudioside A with mogroside V so that the proportion of rebaudioside A to mogroside V is within a range of 95:5 to 99:1 by mass ratio. The proportion of rebaudioside A to mogroside V is preferably 95:5 to 98:2 (mass ratio), and more preferably 96:4 to 98:2 (mass ratio).
[0034]
The stevia extract comprising rebaudioside A targeted herein comprises 90 mass% or more, and preferably 95 mass% or
-15more, of rebaudioside A. Examples include, but are not limited to, stevia extract containing, as other components, steviol glycosides other than rebaudioside A in a total amount of 1 mass% or less; and preferably stevia extract containing stevioside and rebaudioside C in a total amount of 0.2 mass% or less.
[0035]
When mogroside V and rebaudioside A are mixed at the ratio described above, the problems of stevia extract, such as bitterness, lingering sweetness (remaining aftertaste), lack of richness, and slow sweetness expression in the oral cavity, can be improved, and the taste of stevia extract can be brought closer to that of sugar. Therefore, the taste of stevia extract to be improved by the present invention is at least one selected from the group consisting of bitterness, lingering sweetness, richness, and sweetness expression speed in the oral cavity. The qualities of taste are comprehensively improved, i.e., reduction or elimination of bitterness, reduction or elimination of lingering sweetness, enhancement of richness, and higher speed of sweetness expression in the oral cavity, whereby the taste of stevia extract comes closer to that of sugar, and an excellent sweetness quality is imparted.

[0038]
In the following Experimental Examples, stevia extract (Rebaudio J-100, produced by Morita Kagaku Kogyo Co., Ltd.) (dry powder) was used as a rebaudioside A-containing raw material. Rebaudio J-100 is a high-intensity sweetener having sweetness 360 to 460 times that of sugar and comprising 95.2% of rebaudioside A, 0.1% of rebaudioside C, and 0.1% of stevioside (see JP2011115142A). In the following Experimental Examples, this product is referred to as stevia extract.
[0039]
Further, in the following Experimental Examples, siraitia grosvenorii extract (dry powder) was used as a mogroside V-containing raw material. The siraitia grosvenorii extract was prepared as a dry powder by extracting raw fruits (non-dried fruits) of siraitia grosvenorii with water, then collecting the water extraction liquid by filtration, and decolorizing and concentrating the water extraction liquid, followed by spray drying. In the following Experimental Examples, the thus-prepared siraitia grosvenorii extracts comprising 50% and 30% of mogroside V are referred to, respectively, as siraitia grosvenorii extract 1 and siraitia grosvenorii extract 2.
[0040]
Experimental Example 1: Improvement in Taste of Sweetener Composition (1) (1) Preparation of Test Sample
Using the stevia extract and siraitia grosvenorii extract 1 described above, rebaudioside A and mogroside V were mixed at the compounding ratios (mass ratios) shown in Table 1, thereby preparing three types of sweetener compositions (Example 1, and Comparative Examples 1 and 2). The compounding ratio of rebaudioside A and mogroside V shown in Table 1 means the compounding ratio (mass ratio) of each component when the total amount of rebaudioside A and mogroside V is defined as 100 parts (hereinafter the same in Tables 3 and 5). Each of these
-17compositions was added to water to obtain a degree of sweetness (intensity of sweetness) similar to that of a 6% aqueous sugar solution, thereby preparing three types of aqueous solutions (test samples: Example 1-1, and Comparative Examples 1-1 and 21). Further, as a control sample, an aqueous solution was prepared by adding stevia extract (Control Example 1) to water to similarly obtain a degree of sweetness similar to that of a 6% aqueous sugar solution (Control Example 1-1).

[0042] (2) Evaluation of Taste
Six trained panelists engaged in the sensory evaluation of the taste of sweeteners were asked to evaluate the sweetness quality of the test samples (Example 1-1, and Comparative Examples 1-1 and 2-1) prepared above, from four viewpoints, i.e., rough taste (e.g., bitterness), lingering sweetness, richness, and quickness of sweetness expression felt in the oral cavity. Specifically, the sweetness quality of the control sample was set to 0 points, and the sweetness quality of a 6% aqueous sugar solution (positive control) was set to 5 points. As the sweetness quality of the test sample came closer to that of the 6% aqueous sugar solution from the control sample, points were added almost
-18equally one by one. When the sweetness quality became the closest to that of the 6% aqueous sugar solution, the sweetness quality was given 5 points. From the average values of the six panelists, comprehensive evaluation was conducted according to the following criteria.
Evaluation Criteria +++: The average value was 4 or more.
++: The average value was 3 or more and less than 4.
The average value was 2 or more and less than 3.
The average value was 1 or more and less than 2.
The average value was less than 1.
[0043]
Table 2 shows the results.
Table 2
Control sample/ test sample Comprehensive evaluation Specific evaluation
Control Example 1-1 0 points Rough taste, such as bitterness, was felt. Lingering sweetness was felt. Richness was barely felt. Sweetness expression in the oral cavity was slightly slow.
Example 1-1 There was less rough taste, such as bitterness. Lingering sweetness was barely felt. Richness was imparted, and rough taste was hardly felt. Quickness of sweetness expression in the oral cavity was close to that of sugar.
Comparative Example 1-1 + There was less rough taste, such as bitterness. Lingering sweetness was slightly felt. Richness was imparted, and rough taste was hardly felt. Quickness of sweetness expression in the oral cavity was slightly close to that of sugar.
Comparative Example 2-1 + Rough taste, such as bitterness, was slightly felt. Lingering sweetness was felt. Richness was imparted, and rough taste was hardly felt. Quickness of sweetness expression in the oral cavity slightly came close to that of sugar.
These results confirmed that the sweetener composition comprising rebaudioside A and mogroside V at a mass ratio of 96.2:3.8 (Example 1) had less lingering sweetness and had quickness of sweetness expression in the oral cavity closer to that of sugar, compared with the sweetener composition comprising rebaudioside A and mogroside V at mass ratio of 92.7:7.3
-19(Comparative Example 1). Further, as is clear from the results of Comparative Examples 1 and 2, when the total amount of rebaudioside A and mogroside V was set to 100 parts, as the ratio of mogroside V increased to 5 parts or more (conversely, as the ratio of rebaudioside A decreased to 95 parts or less), bitterness and lingering sweetness became stronger, and the sweetness guality tended to become further from that of sugar, in terms of quickness of sweetness expression in the oral cavity. This revealed that a sweetener composition having a sweetness quality close to that of sugar was obtained by adjusting the proportion of rebaudioside A to mogroside V within a range of 95:5 to 99:1 (mass ratio).
[0044]
Experimental Example 2: Improvement in Taste of Sweetener Composition (2) (1) Preparation of Test Sample
Using the stevia extract and siraitia grosvenorii extract 1 or siraitia grosvenorii extract 2 described above, rebaudioside A and mogroside V were mixed at the compounding ratios (mass ratios) shown in Table 3, thereby preparing two types of sweetener compositions (Examples 2 and 3). Each of these compositions was added to water to obtain a degree of sweetness (intensity of sweetness) similar to that of a 6% aqueous sugar solution, thereby preparing two types of aqueous solutions (test samples: Examples 2-1 and 3-1). Further, as a control sample, an aqueous solution of stevia extract (Control Example 1) adjusted to obtain a degree of sweetness similar to that of a 6% aqueous sugar solution (Control Example 1-1) was used, as in Experimental Example 1.

[0045] (2) Evaluation of Taste
Three well-trained panelists were asked to evaluate the sweetness quality of the test samples (Examples 2-1 and 3-1) prepared above, in the same manner as in Experimental Example 1. The sweetness quality of the control sample 1-1 was set to 0 points, and the sweetness quality of a 6% aqueous sugar solution (positive control) was set to 5 points. Table 4 shows the results.
Table 4
Comprehensive evaluation Specific evaluation
Control Example 1-1 0 points Rough taste, such as bitterness, was felt. Lingering sweetness was felt. Richness was barely felt. Sweetness expression in the oral cavity was slightly slow.
Example 2-1 There was less rough taste, such as bitterness. Lingering sweetness was improved. Richness was felt, and there was mellow sweetness. Quickness of sweetness expression in the oral cavity was close to that of sugar.
Example 3-1 There was less rough taste, such as bitterness. Lingering sweetness was improved. Richness was felt, and there was mellow sweetness. Quickness of sweetness expression in the oral cavity came close to that of sugar.
As shown in Table 4, it was confirmed that when either siraitia grosvenorii extract 1 comprising 50% of mogroside V or 15 siraitia grosvenorii extract 2 comprising 30% of mogroside V was used as a mogroside V-containing raw material, a composition having less rough taste (e.g., bitterness) and lingering sweetness, having richness, and having a sweetness quality close
-21to that of sugar was obtained by adjusting the proportion of rebaudioside A to mogroside V in the sweetener composition to 97.3:2.7 (mass ratio). This revealed that, among the components contained in the siraitia grosvenorii extract, mogroside V contributed to the improvement in the sweetness quality of rebaudioside A, particularly the improvement in the sweetness quality of stevia extract comprising 95% or more of rebaudioside A; and that a sweetener composition having a sweetness quality close to that of sugar was obtained by adjusting the proportion of rebaudioside A to mogroside V contained in the stevia extract within a range of 95:5 to 99:1 (mass ratio).
[0046]
Experimental Example 3: Improvement in Taste of Sweetener Composition (3) (1) Preparation of Test Sample
Using the stevia extract and siraitia grosvenorii extract 1 described above, rebaudioside A and mogroside V were mixed at the compounding ratios (mass ratios) shown in Table 5, thereby preparing three types of sweetener compositions (Example 2, and Comparative Examples 3 and 4). As shown in Table 6, these compositions were each added to an aqueous solution (acid aqueous solution) containing 0.1% citric acid and 0.03% trisodium citrate to obtain a degree of sweetness (intensity of sweetness) similar to that of an acid aqueous solution containing sugar at a concentration of 8% (containing 0.1% citric acid and 0.03% trisodium citrate) , thereby preparing three types of acid sugar solutions (pH 3.2) (Example 2-2, and Comparative Examples 3-1 and
4-1). Further, as a control sample, an acid sugar solution was prepared by adding stevia extract (Control Example 1) to the above acid aqueous solution so as to obtain a degree of sweetness similar to that of an acid aqueous solution containing sugar at a concentration of 8% (Control Example 1-2).

Five well-trained panelists were asked to evaluate the sweetness quality of the test samples (Example 2-2, and Comparative Examples 3-1 and 4-1) prepared above. Specifically, the sweetness quality of the control sample (Control Example 1-2) was set to 0 points, and the sweetness quality of an 8% aqueous sugar solution (positive control) was set to 5 points. From two viewpoints, i.e., rough taste (e.g., bitterness) and lingering sweetness, as the sweetness quality of the test sample came closer to that of the 8% aqueous sugar solution from the control sample 1-2, points were added one by one. When the sweetness quality became the closest to that of the 8% aqueous sugar solution, the sweetness quality was given 5 points. From the average scores of the five panelists, comprehensive evaluation was conducted according to the following criteria.
Evaluation Criteria +++: The average value was 4 or more.

The average value was 2 or more and less than 3.
The average value was 1 or more and less than 2.

Comprehensive evaluation Specific evaluation
Control Example 1-2 0 points There was rough taste, such as bitterness. Lingering sweetness was felt.
Example 2-2 +++ Rough taste, such as bitterness, was suppressed. Lingering sweetness was a little, and there was clean taste.
Comparative Example 3-1 + There was, but a little, rough taste, such as bitterness. There was, but a little, lingering sweetness.
Comparative Example 4-1 + There was slight rough taste, such as bitterness. There was lingering sweetness.
These results confirmed that the sweetener composition comprising rebaudioside A and mogroside V at a mass ratio of 97.3:2.7 (Example 2) had less bitterness and lingering sweetness, and the sweetness quality was closer to that of sugar even under acid conditions (pH 3.2) of an acid sugar solution, compared with the sweetener composition comprising rebaudioside A and mogroside V at a mass ratio of 94.5:5.5 (Comparative Example 3). Further, as is clear from the results of Comparative Examples 3-1 and 4-1, when the total amount of rebaudioside A and mogroside V was set to 100 parts, as the ratio of mogroside V increased to 5 parts or more (conversely, as the ratio of rebaudioside A decreased to 95 parts or less), bitterness and lingering sweetness occurred, and the sweetness quality tended to become further from that of sugar. This revealed that even in the case of use under acidic conditions, a sweetener composition having a sweetness quality close to that of sugar was obtained by adjusting the proportion of rebaudioside A to mogroside V contained in the stevia extract within a range of 95:5 to 99:1 (mass ratio).

Example 5: Application to Coffee Beverages
-24The sweetener compositions of Example 2 and Comparative Example 4, each in an amount equivalent to 3% sugar, were added to a beverage obtained by dissolving commercially available instant coffee Blendy (produced by Ajinomoto AGF, Inc.) in hot water, thereby preparing warm coffee beverages (temperature: 70°C) with sweetness. Three well-trained panelists were asked to taste these beverages and compare their taste.

Sensory evaluation Richness was increased, and mellow sweetness was imparted. Quickness of sweetness expression was close to that of sugar, and there was less lingering sweetness. There was no richness. Sweetness expression was slow, and lingering sweetness was felt. Bitterness, sourness, and unpleasant taste that were not derived from coffee were felt.
Note 1: Proportion of rebaudioside A (A) to mogroside V (V) (mass ratio)
As shown in Table 8, it was confirmed that when mixed with a coffee beverage, the sweetener composition comprising rebaudioside A and mogroside V at a weight ratio of 97.3:2.7 (Example 2) imparted rich, mellow sweetness to the coffee beverage. It was also confirmed that because the quickness of sweetness expression came closer to that of sugar, a sweetness quality similar to that of sugar could be imparted (all Example 5). In contrast, when the sweetener composition comprising rebaudioside A and mogroside V at a weight ratio of 81.6:18.4 (Comparative Example 4) was mixed with a coffee beverage, there was no richness-enhancing effect. Further, there was lingering sweetness, and the sweetness quality was far away from that of
-25sugar, in terms of slow sweetness expression (all Comparative Example 5). This reveals that the sweetener composition of the present invention is also useful as a sweetener that can improve the taste of coffee beverages.

Example 6: Application to Fruit-Juice Beverages
20% orange juice-containing beverages (Example 6 and Comparative Example 6) were prepared according to the formulations shown in Table 9. Five well-trained panelists were 10 asked to taste these beverages and compare their taste. As the sensory evaluation, comparative evaluation was performed using, as a positive control (reference beverage), a 20% orange juicecontaining beverage in which high-fructose corn syrup was mixed at a total concentration of 11%, in place of 0.033% of the sweetener composition mixed in Example 6 and Comparative Example
